Van wont start on 1993 Ford Aerostar

I have changed the selenoid and the battery and my van still wont start. Could it be something else

it could be the starter motor, not uncommon for an Aerostar. When you say it won't start, you mean it won't turn over, yes?
yes, does that mean the whole starter or hopefully just the wires:)
